Product Introduction:

May-Grunwald Stain is often used for staining of tissue sections, blood and cell smears, bacteria, chromosome banding, protozoa parasites and so on. It is especially for helicobacter pyloric. Helicobacter pylori is also known as campylobacter pylori. It has been proved that the bacteria is closely related to chronic gastritis and peptic ulcer. Helicobacter pyloric in the stomach is generally arc-shaped, S-shaped or seagull shaped, and sometimes 3-4 bends are seen in spiral shape, often in the shape of fish. Helicobacter pyloric is mostly found between the surface epithelium and the mucosal layer of the gastric mucosa, and close to the surface epithelial cells, some of them enter into the cytoplasm of the epithelial cells, and the bacteria are also found in the gastric fovea and the superficial glandular cavity of the mucosa.
The main staining methods of helicobacter pyloric are Methylene Blue method, Silver Nitrate method, May-Grunwald-Giemsa (MGG) method and Basic Fuchsin method. Silver Nitrate method has a clear contrast and the stained section can be preserved for a long time, but the operation is more time-consuming and troublesome. Other methods are simple and convenient, but the stained section is easy to fade. After May-Grunwald staining, helicobacter pyloric is blue, collagen fiber is red, red blood cell is green, gastric mucosa epithelium is light blue, the nucleus is dark blue.
